Description

This is a part of the SQL:2011 Analytics Complete Umbrella JIRA HIVE-13554. Hive should support multiple subqueries wherever it is mandated. Currently there are many restrictions such as "select * from t1 where t1.x in (select c from t2) and t1.y in (select c from t3);" is not allowed.
